Thermal Shakers are an Epic-rarity material in Arc Raiders, used in high-level Research Station upgrades. They can also be deconstructed into high-level crafting materials after they are successfully brought back to Speranza. That combination makes them useful whether a player is progressing the Research Station directly or needs valuable components for another crafting goal.

The important catch is rarity. An Epic item is not a fixed reward for visiting one building or opening one particular container. Thermal Shakers have been found in Pendola Pass, particularly in areas marked by Technological and Electrical loot themes, but a run through the correct area may still come up empty. Treat the route as a way to improve the odds, not a guarantee.

Where to find Thermal Shakers in Arc Raiders

Start in Pendola Pass. Thermal Shakers are confirmed to appear there following the Frozen Trail update, and the strongest target is the Cielo Sereno Observatory.

The Observatory is a Technological zone and a potentially high-value loot destination. That makes it a sensible first stop for this material, especially when the aim is to look through a concentrated location rather than roam broadly through the map. Still, its high-level loot status does not mean that every visit produces a Thermal Shaker.

Best areas and containers to check

  • Technological locations: These are the primary area type to prioritize in Pendola Pass.
  • Electrical locations: These are also associated with Thermal Shaker spawns and are worth checking when they are available along a route.
  • Cielo Sereno Observatory: A Technological location in Pendola Pass and the most specific recommended destination.
  • Metal crates: Thermal Shakers can appear in these containers.
  • Sliding drawers: Check these even though they are not exclusively tied to one item type.
  • Open shelving: The item can be sitting visibly on shelves rather than hidden in a container.

That last point matters. A search limited to obvious crates can leave loot behind. At the Observatory, make a deliberate pass through both searchable storage and exposed shelf space before deciding the location has been exhausted.

Rarity describes how consistently an item can be expected to appear, not merely how useful it is after acquisition. In practical terms, an Epic Thermal Shaker can be absent even in a suitable Technological or Electrical area. Players should therefore avoid treating a single unsuccessful visit as proof that a location is wrong.

The better approach is to separate two ideas: spawn eligibility and spawn certainty. Pendola Pass has confirmed Thermal Shaker availability, and the Observatory is a strong location to investigate because of its Technological classification. Neither fact turns the item into a guaranteed pickup. Checking the appropriate environment carefully is the controllable part; whether the Epic item appears remains variable.

A practical Pendola Pass search routine

  1. Make Cielo Sereno Observatory the anchor of the trip. It is the clearest known Technological location for a Thermal Shaker search.
  2. Search more than dedicated-looking tech containers. Open metal crates and sliding drawers, then look across shelves and other exposed storage areas.
  3. Include Electrical locations when the route allows. They are another relevant loot type for the item.
  4. Do not overinterpret an empty run. Since Thermal Shakers are Epic, a full sweep can legitimately yield none.
  5. Prioritize getting a found item back to Speranza. A Thermal Shaker only becomes available for Research Station use or deconstruction once it is returned there.

This is a method built around efficient searching rather than a promised drop. The main time saver is knowing that the Observatory’s shelves deserve attention alongside drawers and crates. It also helps to remember that “neutral” containers can hold the item: do not skip them simply because their appearance does not scream “thermal equipment.”

Should you use or deconstruct a Thermal Shaker?

The supplied uses point to two different decisions. Thermal Shakers support high-level Research Station upgrades, but they can also be broken down into high-level crafting items after reaching Speranza. The correct choice depends on the immediate objective.

If a Research Station upgrade specifically calls for the Thermal Shaker, keeping it intact serves that direct progression need. If no current upgrade requires it and another high-level crafting project needs the materials gained through deconstruction, dismantling may be more useful. What should not be assumed is that one choice is universally best: the material has value in both forms.

Because the item is Epic and not reliably found on every route, it is worth checking current station requirements before deconstructing one. That simple check can prevent turning a scarce upgrade component into crafting materials only to discover that the intact item is needed next.

Common mistakes to avoid

  • Searching only one container type. Metal crates and sliding drawers are relevant, but so are items left in the open on shelves.
  • Ignoring loot-zone themes. Technological and Electrical areas are the useful categories; random searching outside them is less focused.
  • Assuming the Observatory guarantees a drop. It is a recommended high-level Technological location, not a fixed Thermal Shaker dispenser.
  • Forgetting the return requirement. The material must make it back to Speranza before it can be used for upgrades or deconstructed.
  • Breaking one down without considering upgrades. Its dual use makes it worth confirming what the Research Station needs first.

For players who enjoy keeping up with the wider PC side of gaming while planning their next material run, this look at Ben Affleck’s long-running competitive-game habit is a reminder that loot routes are far from the only way games can consume an evening.

In short: head to Pendola Pass, make Cielo Sereno Observatory the priority, search Technological and Electrical spaces closely, and inspect shelves as carefully as crates and drawers. An empty run is possible, but that route puts the search in the right loot ecosystem for an Epic Thermal Shaker.
